4 Claims.

The present invention is a division of my copending application Serial No. 66,620 for Cash registers, led March 2, 1936, and refers more particularly to the slidably mounted cash or credit file drawers mounted therein, and has for its object the provision of means for slidably supporting the drawers and for opening them when desired.

The above, together with other objects which will be apparent from the drawings and following description, or which may be later pointed out, may be attained by constructing the improved slidable drawers in the manner illustrated in the accompanying drawings, in which Figure l is a side elevation partly in section showing the lower portion of a register provided with a cash drawer and a credit le drawer embodying the invention taken as on the line Fig. 2;

Fig. 2, a rear elevation, with parts broken away, of the lower portion of the register, showing the two drawers as illustrated in Fig, l taken as on the line 2 2, Fig. 1.

Fig. 3, an enlarged, fragmentary detail sectional view taken as on the line 3 3, Fig. 1; and

Fig. 4, an enlarged, detail sectional view, taken as on the line 4 4, Fig. 1.

And Fig. 5, a plan sectional view taken as on the line 5 5, Fig. 2.

Fig. 6, a perspective view of one drawer, telescopic plate and latching means; and

Fig. 7, a detail sectional view taken as on the line 1 l,.Flg. 1.

Similar numerals refer throughout the drawings.

The invention is illustrated as applied to a combined cash and credit register, but since the present invention is directed to the drawers per se, the register is not illustrated in detail, but only a fragmentary portion thereof is shown and described.

As is usual practice, in registers of the general type indicated, each bank of keys has associated therewith a link connected to a bell crank lever through which the type bars are operated, this link being allowed to move forward by the depression of any key in the corresponding bank.

These links are indicated at 60, and the lower arms of the bell crank levers are shown at 6|, fulcrumed upon the frame at 62 and pivotally connected, as at 63, to the corresponding links.

A rack bar 52, operated by the register in the manner disclosed in my copending application above referred to, may mesh with a pinion 13, fixed upon the sleeve 14 which is slidably keyed to similar parts upon the vertical shaft 75, journaled through the rear portion of the frame of the machine.

'I'he sleeve '14 may be keyed upon the shaft 'l5 as by the longitudinal slot I6 in the sleeve engaging the stud 'll in the shaft. The shaft 'l5 is mounted for vertical sliding movement, as well as for rotation, in its journals.

The lifting lever is provided at its rear end with the angular flange 86 located beneath the collar 8l upon the shaft 'l5 and adapted to be normally located beneath a cut-out portion of said collar (not shown), whereby raising of the lever will permit the angular end 86 thereof to pass upward through said cut-out portion of the collar without moving the shaft l5.

The apparatus illustrated is shown provided with -a cash drawer 89 located beneath the adding and listing mechanism and a credit drawer 90 located beneath the cash drawer. These drawers are slidably mounted within chassis indicated generally at 9| and 92 respectively and enclosed by housings 93 and 94 respectively. A pull spring 95 is provided for norm-ally urging the cash drawer to open position and a pull spring 96 is similarly provided for normally urging the credit drawer to open position.

For the purpose of normally holding the cash drawer in closed position, a latch bolt 91 is vertically slidably mounted within a bracket 98 and normally urged downward as by the spring lill, into the recess 99, formed in a plate |60 extending across the rear upper portion of the cash drawer.

In the same manner, the credit drawer is normally held in closed position by the latch bolt |02 vertically slidably mounted in the bracket |03 and normally urged downward into engagement with the recess |04 in the plate |05, by means of the spring |06.

A lifting bar |01 is pivoted upon some stationary portion of the machine and located through a notch |09 in the rear side of the latch bolt 97. It will be seen that by raising the free end of the lifting bar |07, the latch bolt 91 may be raised out of engagement with the recess 9.9 in the plate |00 of the cash drawer 89, permitting the spring 95 to open said drawer.

A similar lifting bar |0 is pivoted upon some stationary portion of the machine and located through' a notch ||2 in the latch bolt |02, so that by raising the free end of the lifting bar ||0, the latch bolt |02 may be raised out of engagement with the 'recess |04 in the plate |05 of the credit drawer, permitting the spring 96 to open said drawer.

Collars or washers H3 and H4 are fixed upon the sleeve 14 above and below the pinion 13 to form a guide for the same upon the rack bar 52. Just above the upper collar H3 a collar H5 is fixed upon the shaft 15 as by the set screw H6 and provided with a lift nger H1 adapted to be moved to position beneath the free end of the lifting bar |01.

A similar collar H8 is xed upon the lower portion of the shaft 15 as by the set screw H9 and provided with a similar lift finger adapted to be moved into position beneath the free end of the lifting bar H0.

The drawers may be slidably mounted within the chassis frames in any suitable manner, the preferred construction being illustrated, in which the credit drawer 90 is mounted for horizontal sliding movement within the inverted U-shaped chassis frame members 92, by means of a series of channel members and rollers.

For this purpose a channel member |2| is fixed to the inner sides of the U-shaped chassis frames 92 at each side of the drawer 90. An oppositely disposed channel member |22 is telescoped over each channel member |2| and carries a roller |23 which rolls within the channel |2|. This channel |22 is connected to the downturned ends |05a of the plate |05 and to the forwardly disposed angular ends |24 of the bar |25 as by the bolt |26 upon which the roller |23 is journaled, and rides upon the roller |23 mounted on the chassis frame.

Rollers |21 are carried upon the outer sides of the channel |22 and received in a channel |28 fixed to each side of the drawer 90, thus slidably supporting the drawer upon said rollers. For the purpose of taking up any lost motion, the bar |25 has springs |29 xed upon its rear side for engagement with the back wall of the housing when the drawer is in closed position.

The spring 96 may be connected at its forward end to a stud |30 depending from the bar |3| spaced above the bottom wall of the housing as by the studs |32. The rear end of the spring 96 may be connected to the credit drawer catapult |33 which is slidably mounted upon the bar |3| and provided with the upturned angular flange |34 at its rear end for contacting with the rear end of the credit drawer.

Stop members in the form of plates |35 may b e spot welded or otherwise fixed to the rear end of the drawer 90 and depend below the bottom thereof for engagement with the frame portion |36 at the front of the credit drawer housing to prevent the drawer from being accidentally withdrawn entirely from the housing. A bumper |31 is xed upon the bar |3| to limit the forward movement of the credit drawer catapult |33.

A cam bar |38 is fixed to each side of the chassis frame 92 and provided with the tapered forward and rear ends |39 and |40 respectively. A latch lever |4| is pivoted as at |42 upon the side of the drawer and provided at its free end with a reduced extension |43 to which is connected one end of a pull spring |44, the other end thereof being connected to any suitable stationary point upon the drawer, being shown as connected to the rear end of the channel |28. A pin |45 is carried by the lever |4| near the free end thereof for contact with the inclined ends and lower edge of the cam bar |38.

A locking finger |46 depends from each side of the plate |05 and is adapted to engage the free end of the latch lever |4| as shown inv Fig. 2, the lower end of said finger being inclined forwardly and upwardly as at |41 for a purpose to be later described.

A stop block |48 may be fixed upon each side of the credit drawer 90 just beyond the rear end of the channel |28 for engagement with the rearmost roller |21 as the drawer is opened. One or more stop pins |49 may be carried upon leaf springs |50 fixed at their rear ends to the underside of the plate |05, said stop pins being adapted for engagement with the front frame portion |5| of the credit drawer housing.

For the purpose of slidably mounting the cash drawer within its housing, a channel |52 may be xed to each side of the cash drawer 89- as Well as to the depending anges |000. of the plate |00, said channel being arranged to roll upon rollers |53 carried by the chassis members 9|. Rollers |54 are carried by the drawer 89 and adapted to roll in the channel members |55 fixed to the chassis members 9|.

A cash drawer catapult |56 is slidably mounted upon the bar |51 spaced above the bottom wall of the cash drawer housing as by the studs |58, said catapult being provided with a bumper |59 for engagement with the rear end of the cash drawer. The spring 95 is connected at its forward end to a pin |60 depending from the bar |51 and at its rear end to the catapult |56. A stop block |6| is xed upon the bar |51 to limit the forward movement of the catapult |56. Depending stop fingers |62 are provided at the rear end of the cash drawer 89 for engagement with the front portion |63 of the cash drawer housing to prevent accidental displacement of the cash drawer from the housing.

Assuming that a cash transaction is to be made, when the amount is set up and the proper keys have been depressed, the corresponding link 60 will be allowed to move forward, as in usual practice, by the operation of the machine, and the rack bar 52 will be operated in the manner disclosed in my copending application above referred to.

During this operation of the rack bar the pinion 13 will be rotated, and in turn will rotate the shaft l 15 to a position bringing the lift finger H1 beneath the free end of the lifting bar |01, and rotating the collar 81 upon said shaft to such position that the cut-out portion of said collar is not located above the angular end 86 of the lifting lever 85. As the operation of the machine progresses the lever 85 will be lifted, the angular end 86 thereof engaging the collar 81 and slidably moving the shaft 15 upward.

The lift finger H1 having been positioned beneath the free end of the lifting bar |01, this upward movement of the shaft 15 will raise the lifting bar |01 and through the same will raise the latch bolt 91, against the pressure of the spring |0|, out of engagement with the recess 99 in the plate |00, releasing the cash drawer and permitting the spring 95, acting through the cash drawer catapult |56, to quickly slide the cash drawer into open position.

As the lifting bar 01 is raised to withdraw the latch bolt 91 and release the cash drawer, the pin |68 carried by said lifting bar will be raised out of engagement with the end of the tapper |65, permitting the spring |91 to cause the tapper to strike the gong |64 a sharp blow, giving an audible signal that the cash drawer is being opened.

If a charge transaction is made, the amount may be set up in the machine, and the proper keys are depressed in order that the credit drawer will be opened when the machine is operated. As

disclosed in my copending application above referred to, the rack bar 52 will be operated suilcientlyl to rotate the shaft 'I5 so as to bring the lift iinger of the collar ||8 beneath the free end of the lifting bar H0.

Thus, when the shaft 'l5 is raised by means of the lifting lever 85, the lift nger will raise the lifting bar IIU, pulling the latch bolt |02 out of the recess lllli of the plate |05, releasing the credit drawer and permitting the spring operated catapult I 33 to push the credit drawer open.

As the drawer moves. toward open position, the pin |45 on the lever |4| will ride down the inclined end |40 of the cam bar |38 and onto the lower edge of said cam bar, releasing the lever |4| from engagement with the nger |46, thus disconnecting the plate |05 from the credit drawer so that as said drawer is pulled out to the fully opened position, the accounts at the rearmost end of the drawer will be accessible.

I claim:
